This 1.25ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG843658928 or 843658928. Listed at 10 retailers as of October 29, 2026, with prices from $266 to $1,021, a $755 spread on the same certified stone. MOH London lists it at $1,021. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
